[0002] The display screen of the washing machine is a screen that can display and control the washing machine by touch. During the use of the display screen, frequent power on and off of the display screen will shorten its service life. Summary of the invention

[0003] The purpose of the present application is to provide a display control screen control method, a control device and a washing device, aiming to solve the problem of frequent consumption of the life of the display control screen in the related art.

[0004] In a first aspect of an embodiment of the present application, a display control screen control method is proposed, wherein the display control screen is applied to a washing device, and the display control screen includes a display module and a touch module. The method includes: Acquire a first power-off time interval, wherein the first power-off time interval is a period of time within a preset single cycle, and is used to control the display control screen to be powered off within the first power-off time interval; In a preset interval correction cycle, if the washing device is in use during the first power-off time interval, the power supply of the display module and the touch module is controlled according to the operation of the washing device and the interaction of the display control screen, and the first use time period is recorded; if the washing device is in use outside the first power-off time interval, the second use time period is recorded; wherein the interval correction cycle includes at least one single cycle; When the actual usage time of the washing device reaches the interval correction period, the first usage time period and the second usage time period are processed to obtain a second power-off time interval to control the display control screen to be powered off within the second breakpoint time interval.

[0005] With this embodiment, in the process of controlling the display control screen, the first usage time period and the second usage time period will be collected within the interval correction period. Since the first usage time period and the second usage time period are both the actual usage time of the display control screen, the second power-off time interval obtained according to the first usage time period and the second usage time period conforms to the actual usage of the display control screen, which is helpful to control the power off of the display control screen in the second power-off time interval, which will not affect the normal use of the display control screen, and can reduce the service life of the display control screen consumed by frequent switching on and off. At the same time, within the interval correction period, if the washing device is in use within the first power-off time interval, the power supply of the display module and the touch module will be controlled according to the operating conditions and the interaction conditions, which is conducive to reducing the power consumption of the display module and the touch module and extending the service life of the display module and the touch module, thereby extending the service life of the display control screen.

[0006] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the processing of the first usage time period and the second usage time period to obtain a second power-off time interval includes: Performing linear processing on the first usage time period and the second usage time period, and discarding the first usage time period and the second usage time period whose deviations exceed a preset deviation threshold; The latest end time of the remaining first usage time period and the second usage time period is used as the start time of the second power-off time interval, and the earliest start time of the usage is used as the end time of the second power-off time interval, or the preset first time point after the latest end time of the remaining first usage time period and the second usage time period is used as the start time of the second power-off time interval, and the preset second time point before the earliest start time of the usage is used as the end time of the second power-off time interval.

[0007] By adopting this embodiment, the first usage time period and the second usage time period with large deviations are discarded through linear processing, which can improve the accuracy of the obtained second power-off time interval, thereby determining a second power-off time interval that is more in line with the actual usage needs of the display and control screen, avoiding the display and control screen being powered on when the display and control screen is powered off due to inaccurate second power-off time interval, increasing the number of power-off switching times on the display and control screen, and easily extending the service life of the display and control screen.

[0008] In combination with the first aspect, in an optional implementation of the embodiment of the present application, after obtaining the second power-off time interval, the method further includes: If the washing device is in use during the second power-off time interval within the single cycle and the number of times exceeds a preset threshold, the interval correction cycle is entered again to retrieve the first usage time period and / or the second usage time period and determine the second power-off time interval based on the retrieved first usage time period and / or the second usage time.

[0009] According to this embodiment, if the washing equipment is in use during the second power-off time interval, it proves that the actual use time of the washing equipment has changed. At this time, when entering the interval correction cycle again, the first use time period and / or the second use time period can be determined according to the actual use time of the washing equipment, so as to realize the correction of the second power-off time interval, ensure the accuracy of the subsequent power-off time of the display and control screen, reduce the switching frequency of power failure on the display and control screen, and extend the service life of the display and control screen.

[0010] In combination with the first aspect, in an optional implementation of the embodiment of the present application, controlling the power supply of the display module and the touch module according to the operation status of the washing device and the interaction status of the display control screen includes: If the washing device is not running, but the display control screen is interactive, the display power control circuit of the control screen is disconnected to stop supplying power to the display module in the display control screen; the touch power control circuit is turned on to supply power to the touch module in the display control screen; Alternatively, if the display control screen has no interaction, but the washing device is running, the touch power control circuit is controlled to be disconnected to stop supplying power to the touch module in the display control screen; the display power control circuit is controlled to be turned on to supply power to the display module in the display control screen; The first end of the screen display power control circuit is connected to the display module, and the second end is connected to the display module power supply; The display module power supply is used to supply power to the display module; A first end of the touch power control circuit is connected to the touch module, and a second end is connected to a touch module power supply; The touch module power supply is used to supply power to the touch module.

[0011] With this embodiment, the display module and the touch module can be powered independently, which is conducive to reducing the power-on time of the display module and the touch module, thereby reducing power consumption and extending the service life of the display control screen. When the washing device is not in use, but the display control screen is interactive, the screen display power control circuit is controlled to be disconnected to stop supplying power to the display module in the display control screen. The touch power control circuit is controlled to be turned on to power the touch module in the display control screen. More refined energy saving is achieved.

For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0025] Smart homes are developing rapidly, and the operating method of washing machines is developing from traditional mechanical buttons to touch controls. The principle of TFT screens is to detect changes in capacitance to determine touch signals. This method of determination has a problem of rapidly decreasing lifespan in actual washing machine applications. Long-term power supply to the washing machine screen will lead to static electricity accumulation and liquid crystal polarization, and the interface is easily affected by high temperature and high humidity, affecting its use effect.

[0026] Based on this, the embodiments of the present application provide a display screen control method, a control device and a washing device, which ensure that the LCD screen can display normally in the washing machine and extend its service life.

[0027] Specifically, the display control screen control method, control device and washing device provided in the embodiments of the present application solve at least one of the following problems: 1. The washing machine has a standby wake-up function. Long-term power supply will cause high loss to the LCD screen interface and easily damage it. The unified power-off method is not suitable for the current system with multiple detection components; 2. The washing machine takes a long time to run the washing and drying program. The screen is prone to accumulate static electricity over a long period of time. Static electricity accumulation over a long period of time will damage the touch chip and capacitor module of the LCD screen. 3. When the LCD screen is powered on for a long time and the screen is kept still, it is easy to cause liquid crystal polarization, resulting in residual images on the screen or yellowing of the screen; 4. Frequent power supply and power failure of the LCD screen may cause damage to the interface; 5. Infrared detection results are greatly affected by factors such as ambient temperature, humidity, and background radiation, which may lead to misjudgment.

[0028] It can have the following beneficial effects: The machine learning method is used to control the power supply and signal of the LCD circuit on and off at a fixed time, avoiding interface loss caused by frequent switching of the LCD screen. The auxiliary feedback control circuit detects the use status of the washing machine, dynamically turns on the screen display and touch detection, and assists the machine learning method for supplementary control. By adding an ultrasonic sensor, combined with the washing machine status and washing machine process, it is determined whether the washing machine is being operated. This solution adds two control circuits and combines the machine learning control method to learn the user's usage habits, regularly disconnect the power of the touch and LCD when the washing machine is idle, and regularly turn on the power of the touch and LCD during the use period, which can avoid the screen life being wasted ineffectively.

[0029] Have at least one of the following characteristics: 1. Use machine learning to learn user habits and perform timed on / off of touch and LCD power and signal lines. Compared with real-time detection, it reduces the on / off times of the screen display and touch control circuits. 2. Add ultrasonic sensors and auxiliary circuits to provide peripheral devices that support automatic control of the washing machine screen and touch switches, and assist in judgment in the early stages of machine learning; 3. Add touch protection logic for washing machines. By controlling the power supply and signal on / off of the touch module of the washing machine, the power is cut off regularly to release the static electricity on the screen, so as to prevent the damage to the touch module caused by static electricity accumulation and extend the use time of the touch module. 4. Add screen protection logic for the washing machine. By controlling the power supply and signal on / off of the washing machine touch module, the power supply of the display module and all signal lines are regularly cut off to prevent the display module from being in a voltage state for a long time, causing problems such as screen polarization and liquid crystal aging, thereby extending the service life.

[0030] Next, a display control screen control method provided by the present application is further described. Figure 1 The flowchart of the display control screen control method shown in the figure is that the display control screen is applied to a washing device, the display control screen includes a display module and a touch module, and the display control screen control method includes the following steps: S10: Obtain a first power-off time interval.

[0031] Among them, the first power-off time interval is a period of time within a preset single cycle, which is used to control the display control screen to be powered off within the first power-off time interval. Specifically, when it is necessary to control the power-off time of the display control screen, first determine the usage time period of the display control screen, that is, the user often has a demand for the display control screen during that time period. Based on this, a first power-off time interval is preset, and the first power-off time interval can be any time period when it is not easy for the user to use the washing equipment, such as 2-4 am. The single cycle is used to detect the user's use of the display control screen within a cycle time length, which can be one day, two days or a week, and this embodiment does not make specific limitations on this.

[0032] S12. Within the preset interval correction cycle, if the washing device is in use within the first power-off time interval, the power supply of the display module and the touch module is controlled according to the operation status of the washing device and the interaction status of the display control screen, and the first usage time period is recorded; if the washing device is in use outside the first power-off time interval, the second usage time period is recorded.

[0033] The interval correction period includes at least one of the single periods. Specifically, the interval correction period is used to obtain a sufficient amount of the first usage time period and / or the second usage time period, so the time length of the interval correction period is greater than the time length of the single period. For example, the interval correction period can be 30 days, and the single period can be 1 day or 7 days. Preferably, the single period is 1 day.

[0034] S14. When the actual usage time of the washing device reaches the interval correction period, the first usage time period and the second usage time period are processed to obtain a second power-off time interval.

[0035] In one embodiment, after the second power-off time interval is obtained, the display control screen can be controlled to be powered off when the actual time reaches the second power-off time interval during the actual use of the washing device.

[0036] In the process of controlling the display control screen, the first usage time period and the second usage time period will be collected within the interval correction period. Since the first usage time period and the second usage time period are both the actual usage time of the display control screen, the second power-off time interval obtained according to the first usage time period and the second usage time period conforms to the actual usage of the display control screen, which is helpful to control the power off of the display control screen in the second power-off time interval, which will not affect the normal use of the display control screen, and can reduce the service life of the display control screen consumed by frequent switching on and off. At the same time, during the interval correction period, if the washing equipment is in use during the first power-off time interval, the power supply of the display module and the touch module will be controlled according to the operating conditions and the interaction conditions, which is conducive to reducing the power consumption of the display module and the touch module and extending the service life of the display module and the touch module, thereby extending the service life of the display control screen.

[0037] Optionally, in an implementation of this embodiment, the processing the first usage time period and the second usage time period to obtain a second power-off time interval includes: Performing linear processing on the first usage time period and the second usage time period, and discarding the first usage time period and the second usage time period whose deviations exceed a preset deviation threshold; The latest end time of the remaining first usage time period and the second usage time period is used as the start time of the second power-off time interval, and the earliest start time of the usage is used as the end time of the second power-off time interval, or the preset first time point after the latest end time of the remaining first usage time period and the second usage time period is used as the start time of the second power-off time interval, and the preset second time point before the earliest start time of the usage is used as the end time of the second power-off time interval.

[0038] In one embodiment, linear processing refers to linear calculation of the first use time period and the second use time period. Specifically, coordinate the start time of all the first use time period and the second use time period, where the horizontal coordinate is the date and the vertical coordinate is the start time, so that many coordinate points can be obtained, and a line segment that conforms to the distribution law of most coordinate points is determined based on these coordinate points, so that most (for example, 80%) coordinate points are on or near this line segment. Then, the coordinate points far from the line segment are discarded. Specifically, the deviation threshold can be set according to the actual situation, for example, the deviation threshold can be 50%. Preferably, taking the deviation threshold of 50% as an example, first determine the coordinate points close to the line segment, which account for 80% or more of all coordinate points, and then determine the farthest distance L from the line segment from these coordinate points, and then discard all coordinate points whose distance from the line segment exceeds 50%L. The end time is the same as the start time, and no further description is given.

[0039] By adopting this embodiment, the first usage time period and the second usage time period with large deviations are discarded through linear processing, which can improve the accuracy of the obtained second power-off time interval, thereby determining a second power-off time interval that is more in line with the actual usage needs of the display and control screen, avoiding the display and control screen being powered on when the display and control screen is powered off due to inaccurate second power-off time interval, increasing the number of power-off switching times on the display and control screen, and easily extending the service life of the display and control screen.

[0040] Optionally, in an implementation of this embodiment, after obtaining the second power-off time interval, the method further includes: If the washing device is in use during the second power-off time interval within the single cycle and the number of times exceeds a preset threshold, the interval correction cycle is entered again to retrieve the first usage time period and / or the second usage time period and determine the second power-off time interval based on the retrieved first usage time period and / or the second usage time.

[0041] According to this embodiment, if the washing equipment is in use during the second power-off time interval, it proves that the actual use time of the washing equipment has changed. At this time, when entering the interval correction cycle again, the first use time period and / or the second use time period can be determined according to the actual use time of the washing equipment, so as to realize the correction of the second power-off time interval, ensure the accuracy of the subsequent power-off time of the display and control screen, reduce the switching frequency of power failure on the display and control screen, and extend the service life of the display and control screen.

[0042] Optionally, in an implementation of this embodiment, controlling the power supply of the display module and the touch module according to the operation of the washing device and the interaction of the display control screen includes: If the washing device is not running, but the display control screen is interactive, the display power control circuit of the control screen is disconnected to stop supplying power to the display module in the display control screen; the touch power control circuit is turned on to supply power to the touch module in the display control screen; Alternatively, if the display control screen has no interaction but the washing device is running, the touch power control circuit is controlled to be disconnected to stop powering the touch module in the display control screen; the display power control circuit is controlled to be turned on to power the display module in the display control screen.

[0043] The first end of the screen display power control circuit is connected to the display module, and the second end is connected to the display module power supply. The display module power supply is used to supply power to the display module.

[0044] A first end of the touch power control circuit is connected to the touch module, and a second end is connected to a touch module power supply; the touch module power supply is used to supply power to the touch module.

[0045] In this embodiment, the above-mentioned screen display power supply control circuit can be set between the above-mentioned processor and the above-mentioned display module power supply. The above-mentioned screen display power supply control circuit is connected to the input and output IO pins of the processor and is controlled by the processor. A switch device is provided in the screen display power supply control circuit. When the switch device is closed, the display module power supply and the display module are connected to supply power to the display module. When the switch device is disconnected, the display module power supply and the display module are disconnected, and power supply to the display module is stopped. Among them, the switch device can use a triode or a metal oxide semiconductor (Metal-Oxide-Semiconductor, MOS) tube.

[0046] In this embodiment, the above-mentioned touch power control circuit can be set between the above-mentioned processor and the above-mentioned touch module power supply. The above-mentioned touch power control circuit is connected to the input and output IO pins of the processor and is controlled by the processor. A switch device is provided in the touch power control circuit. When the switch device is closed, the touch module power supply and the touch module are connected to supply power to the touch module. When the switch device is disconnected, the touch module power supply and the touch module are disconnected, and power supply to the touch module is stopped. Among them, the switch device can use a triode or a metal oxide semiconductor (Metal-Oxide-Semiconductor, MOS) tube.

[0047] In the above-mentioned technical solution of the present application, the display module and the touch module can be powered independently, which is conducive to reducing the power-on time of the display module and the touch module, thereby reducing power consumption and extending the service life of the display control screen. When the washing device is not in use, but the display control screen is interactive, the screen display power control circuit is controlled to be disconnected to stop supplying power to the display module in the display control screen. The touch power control circuit is controlled to be turned on to supply power to the touch module in the display control screen. More refined energy saving is achieved. When the display control screen is not interactive, but the washing device is in use, the touch power control circuit is controlled to be disconnected to stop supplying power to the touch module in the display control screen. The screen display power control circuit is controlled to be turned on to supply power to the display module in the display control screen. More refined energy saving is achieved. The touch and display functions in the washing device are designed to be non-interfering and independent of each other, so as to achieve more refined energy saving and improve the energy saving level.

[0048] Optionally, in an implementation of this embodiment, determining that the display and control screen has no interaction includes: when the duration of no screen touch signal and ultrasonic detection signal is detected to be greater than or equal to a predetermined time threshold, or the power button is not pressed, determining that the display and control screen has no interaction.

[0049] In this embodiment, the screen is continuously detected to detect whether the screen is touched. When the screen is touched, a touch signal is generated. If there is no screen touch signal, it means that the screen is not touched. If there is no ultrasonic detection signal, it means that there is no one in front of the washing device. The duration of no screen touch signal and ultrasonic detection signal is counted. If the duration is greater than or equal to the predetermined time threshold, the above time threshold can be flexibly set. For example, it can be set to 5 minutes. Controlling the touch power control circuit to disconnect can stop powering the touch module in the above-mentioned display and control screen, thereby saving energy. Among them, the ultrasonic detection signal can be obtained by setting an ultrasonic sensor on the washing device. Specifically, when there is someone in the monitoring area of ​​the ultrasonic sensor, an ultrasonic detection signal is generated. Preferably, the ultrasonic sensor is arranged on one side of the display and control screen.

[0050] In this embodiment, the fact that the power button is not pressed can be regarded as a condition that the display and control screen is in a non-interactive state. Even if the washing device is powered on and the power button is not pressed, it is also regarded as a condition that the display and control screen is in a non-interactive state.

[0051] Therefore, in some embodiments, although it is detected that the washing device is powered on, if the power button is not pressed, the touch power control circuit and the screen display power control circuit are controlled to be in a disconnected state. In this case, the processor is powered on to enter the default working mode, and the touch power control circuit and the screen display power control circuit are controlled to be in a disconnected state by default. In this case, the display module and the touch module in the display control screen are not powered on. This is beneficial to avoid the waste of electric energy and to improve the service life of the display control screen.

[0052] In this embodiment, when the washing machine is initially powered on and the power button has not been pressed, the processor is powered on to enter the default working mode, and the touch power control circuit and the screen display power control circuit are controlled to be in a disconnected state by default. In this case, the display module and the touch module in the display control screen are not powered on. This is beneficial to avoid the waste of electric energy and to improve the service life of the display control screen.

[0053] By adopting this embodiment, the ultrasonic detection signal is not easily interfered by factors such as temperature and humidity, which is conducive to improving the accuracy of determining that the display screen has no interaction.

[0054] Optionally, in an implementation of this embodiment, determining that the washing device is not running includes one of the following conditions: The washing device is in an off mode; The power button is not pressed; The processor enters a low-power mode.

[0055] The washing machine is in shutdown mode, which can be regarded as the washing machine is not in use.

S101 sets the initial disconnection time period of the LCD screen circuit (including the touch and screen display control circuit) to 2:00-4:00 in the morning, and the machine learning cycle to 30 days; S102 Check at a fixed time every day (0:00 am in this example) whether the machine learning cycle has been reached. If it has reached 30 days, execute S106, otherwise execute step S103; S103: Detect whether the user uses the washing machine during the LCD screen circuit disconnection period by using the ultrasonic sensor and the switch button. If the user uses the washing machine, execute S104 auxiliary circuit control logic flow; if not, execute S105; S104 auxiliary circuit control logic flow is divided into screen display auxiliary control and touch auxiliary control.

[0078] Figure 5 This is a control flow chart of the screen display power supply circuit according to an embodiment of the present invention, as shown in the figure, S301 After the washing machine is powered on, the controller supplies power to the main chip, and the main chip enters the default working mode. The touch power control circuit and the screen display power control circuit are turned off by default. Check whether the washing machine is in the on state, that is, not in the low power mode. If it is in the on state, execute S302, otherwise execute step S303 for judgment; In this embodiment, after the washing machine is powered on, the controller supplies power to the processor, the processor enters the default working mode, and the touch power control circuit and the screen display power control circuit are turned off by default. The power-on state is the non-low power mode state.

[0079] S302: Keep the screen display power circuit turned on to continuously supply power to the display module; In this embodiment, the screen display power control circuit remains turned on and can continuously supply power to the display module.

[0080] S303 detects whether the user presses the power button, if so, executes S304, otherwise, executes step S305 for further determination; S304: Turn on the screen display power circuit and execute the screen module initialization code; In this embodiment, when the screen display power control circuit is turned on and initialized, the screen module initialization code is executed.

[0081] S305 determines through logic whether the washing machine is about to enter a low power consumption state. If the washing machine is in a low power consumption state, execute S307; otherwise, execute step S306; In this embodiment, the working mode of the processor includes a normal working mode and a low power working mode. After entering the low power mode, the processor will change the working frequency and cut off the detection and output of certain peripherals.

[0082] S306: Keep the screen display power circuit turned on and continue to detect whether the washing machine is about to enter a low power consumption state; In this embodiment, the screen display power control circuit remains turned on, and can continuously supply power to the display module, so that the display module continues to work.

[0083] S307 turns off the screen display power circuit, cuts off the power supply and signal circuit of the display module, and the display module stops working.

[0084] In some embodiments, the above method may further include the following steps: when the display and control screen is in an interactive state, controlling the touch power control circuit to close to supply power to the touch module in the above display and control screen.

[0085] In this embodiment, when the display control screen is in an interactive state, the touch module in the display control screen needs to be used. In this case, the touch power control circuit needs to be controlled to be closed to power the touch module in the above-mentioned display control screen.

[0086] In some embodiments, determining that the display control screen is in an interactive state includes at least one of the following situations: detecting a screen touch signal; detecting an ultrasonic detection signal.

[0087] In this embodiment, detection of a screen touch signal can be considered as an interactive state of the display control screen.

[0088] The touch module in the display control screen can generate a screen touch signal when the screen is pressed and touched. The processor determines that the display control screen is in an interactive state based on the received screen touch signal, and then controls the power supply to the touch module in the display control screen.

[0089] In this embodiment, the detection of the ultrasonic detection signal can be regarded as the display control screen being in an interactive state.

[0090] An infrared sensor can be installed on the side of the washing machine touch screen to detect whether a user is close to the operation panel. When a user is detected close to the operation panel, an ultrasonic detection signal is sent to the processor. The processor determines that the display and control screen is in an interactive state based on the received ultrasonic detection signal, and then controls the power supply to the touch module in the display and control screen.

[0091] In this embodiment, when both the screen touch signal and the ultrasonic detection signal are detected, it can be determined that the display control screen is in an interactive state, and then the touch module in the display control screen is controlled to be powered.

[0092] Figure 6 This is a control flow chart of a touch power supply circuit according to an embodiment of the present invention, as shown in the figure. S401 detects whether the screen returns a touch signal, if there is a signal, execute step S403, if not, execute S202; S402 detects whether the ultrasonic sensor has a signal of a user approaching; if there is a signal, execute step S403; if not, execute step S406; S403: Determine whether the touch power circuit is currently in an on state, if not, execute step S405, otherwise, execute step S404; S404: Keep the touch power circuit in the current on state; In this embodiment, when the touch power control circuit remains closed, the touch module can be continuously powered.

[0093] S405: Turn on the touch power circuit and execute the touch module initialization code; In this embodiment, the touch power control circuit is turned on in order to connect the touch module to the touch power supply, realize power supply, and execute the touch module initialization code.

[0094] S406: maintaining the current state of the touch power circuit, if it is on, it remains on, and if it is off, it remains off; S407: Continue to execute step S401 for five minutes; if a screen touch signal or ultrasonic sensor signal is detected within five minutes, execute according to the process, and restart the timer for five minutes until the signal ends, otherwise execute step S408; S408 turns off the touch power circuit, cuts off the power supply and signal circuit of the touch module, and the touch module stops working.

[0095] In this embodiment, the touch power control circuit is disconnected to power off the touch module.

[0096] The technical solution of the present application adds two power control circuits, which dynamically shut down the screen display and touch detection by detecting the status of the washing machine, and perform static electricity release and screen protection. By setting an infrared sensor, combined with the washing machine status and washing machine process, it is determined whether the washing machine is being operated, and two power control circuits are set. In combination with the processor low power mode, the power of touch detection is disconnected when the washing machine is idle, and the power of screen display is disconnected when the machine is shut down, which can avoid the screen life being consumed ineffectively. Infrared sensors and auxiliary circuits are added to provide peripheral devices that support automatic control of the screen display and touch switch of the washing machine. Add the touch protection logic of the washing machine, control the power supply and signal on and off of the washing machine touch module through conditions, regularly cut off the power to release the static electricity of the screen, prevent the accumulation of static electricity from damaging the touch module, and extend the use time of the touch module; add the screen protection logic of the washing machine, control the power supply and signal on and off of the washing machine touch module through conditions, and regularly cut off the power supply of the display module to prevent the display module from being in a voltage state for a long time, causing problems such as screen polarization and liquid crystal aging, and extend the service life.
